Description

Technical Field

[0002] The existing precast corridor structure is conventionally a circular arch opening type structure, which is assembled by cast-in-place concrete through high-strength steel bars. Various embedded parts are fixed according to the designed positions, and the inner and outer formworks coated with release agent are assembled, and the concrete is poured manually. The traditional circular arch opening type precast corridor has a thin thickness and poor stiffness. The cast-in-place concrete construction has a large workload of formwork and side bottom corner bearing frame support, slow construction speed, high cost and high safety risk, making it difficult to achieve rapid construction, and the construction period often cannot meet the requirements, which greatly restricts the construction progress of the overall construction of the sand and gravel and concrete production systems.

[0003] In some prefabrication constructions, after the corresponding modules are hoisted to the approximate positions, subsequent alignment, stabilization and welding work are required. Because there are large tolerances between modules in prefabrication construction itself, larger deviations are likely to occur under external force factors before welding + epoxy glue positioning, resulting in unsatisfactory final data after the modules are finally fixed, leaving greater error hidden dangers for subsequent construction.

[0004] Therefore, there is a need for a resilient stabilizing structure and a precast corridor that can play a more effective stabilizing and supporting role, reduce the offset error between precast modules, and can effectively replace the cast-in-place concrete construction, and is efficient and safe to meet the needs of the existing environment.

[0027] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model with reference to the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0031] Embodiment 1

[0032] Referring to Figures 1 to 3 , it is the first embodiment of the present utility model, and this embodiment provides a resilient and stable structure.

[0033] The activation assembly 100 is used to control the triggering of the resilient and stable structure. The precast bottom mold 101 is arranged at the bottom of the whole set of devices to provide support for the operation of the structure. On the top surface of the precast bottom mold 101, a plurality of insertion cavities 102 are opened for subsequent cooperation. A resilient plate 103 is elastically arranged at the bottom of the insertion cavity 102, and the resilient plate 103 will descend and drive the activation of the stable assembly 200 after being subjected to pressure.

[0034] On the side wall of the precast bottom mold 101, a plurality of telescopic rods 201 are slidably arranged, and each telescopic rod 201 corresponds to an insertion cavity 102. A stabilizing claw 202 is fixedly arranged at the front end of the telescopic rod 201, and the stabilizing claw 202 is located in the insertion cavity 102. The side wall of the telescopic rod 201 is elastically connected to the inner wall of the precast bottom mold 101. In the default state, the telescopic rod 201 is in a compressed state.

[0035] After the resilient plate 103 is subjected to pressure, it can unlock and activate the stable assembly 200. The pressure accumulated by the telescopic rod 201 is released, which will drive the stabilizing claw 202 to quickly push forward, support and strengthen the precast module to be stabilized, and prevent the tolerance from increasing due to misalignment.

[0036] Embodiment 2

[0037] Referring to Figures 1 to 4 , it is the second embodiment of the present utility model. Different from the previous embodiment, the structure of the protection assembly 100 and the cooperation structure of the elastic assembly 200 are further optimized.

[0038] The side wall of the prefabricated bottom mold 101 is fixedly provided with a sliding groove 101a. Each sliding groove 101a corresponds to the telescopic rod 201. The telescopic rod 201 can slide horizontally along the sliding groove 101a. The control board 201a is located at the end of the telescopic rod 201 and is externally arranged outside the side wall of the prefabricated bottom mold 101. When needed, the control board 201a can be pulled to drive the control board 201a to return to its original position.

[0039] On both sides of the telescopic rod 201, there are fixedly extended bump blocks 201b. On one side of the bump block 201b, an elastic telescopic rod 201b-1 is fixed. The other end of the elastic telescopic rod 201b-1 is connected to the inner wall of the prefabricated bottom mold 101. In the default state, the telescopic rod 201 is compressed, and the elastic telescopic rod 201b-1 is also compressed accordingly to accumulate elastic force.

[0040] The front end of the stabilizing claw 202 extends into the insertion cavity 102. The rebound plate 103 arranged at the bottom of the insertion cavity 102 is fixedly connected to the bottom of the insertion cavity 102 through a spring 103a. A prolongation plate 103b is fixedly arranged on the side of the rebound plate 103. On the other side of the prolongation plate 103b, a limiting rod 103b-1 is fixedly arranged. The limiting rod 103b-1 is in contact with the other side of the bump block 201b, and the limiting rod 103b-1 can block the bump block 201b when it is in contact with the bump block 201b.

[0041] When the rebound plate 103 descends under pressure, it will drive the prolongation plate 103b and the limiting rod 103b-1 to descend together. After the limiting rod 103b-1 and the bump block 201b are misaligned, they can no longer block the bump block 201b. Then, the bump block 201b and the telescopic rod 201 will be quickly pushed forward under the action of the elastic telescopic rod 201b-1 to support and strengthen the prefabricated module to be stabilized, preventing the tolerance from increasing due to misalignment.

[0042] Embodiment 3

[0043] Refer to Figures 1 to 5 , which is the third embodiment of the present utility model. Based on the above embodiment, a prefabricated corridor is added.

[0044] The support component 300 is used to support the construction process of the entire precast corridor. Prefabricated side molds 301 are arranged on both sides of the precast bottom mold 101. The prefabricated side molds 301 are initially aligned with the precast bottom mold 101 through forms such as hoisting. An insertion bolt 301a is fixedly arranged at the bottom of the precast bottom mold 101. The insertion bolt 301a will enter the insertion cavity 102 following the movement of the prefabricated side mold 301. Eventually, the insertion bolt 301a contacts the spring-back plate 103 at the bottom of the insertion cavity 102, pushing the spring-back plate 103 to decrease under pressure, causing the linkage limit rod 103b-1 and the convex block 201b to be misaligned. Finally, the convex block 201b and the telescopic rod 201 will be quickly pushed forward under the action of the elastic telescopic rod 201b-1, playing a role in strengthening the support for the insertion bolt 301a.

[0045] A plurality of steel bar holes 101b are also fixedly arranged at the top of the precast bottom mold 101 to correspond to multiple reinforcing ribs 301b arranged at the bottom of the prefabricated side mold 301. The reinforcing ribs 301b are inserted into the steel bar holes 101b, and subsequent installation can be closed through the grouting process. The arched roof plate 302 is arranged on the top of the prefabricated side mold 301, and the two prefabricated side molds 301 support the arched roof plate 302.

[0046] An auxiliary chute 301c is fixedly opened at the top of the prefabricated side mold 301. A drag reduction sliding piece 301c-1 is embedded in the inner wall of the auxiliary chute 301c. A protruding section 302a is fixedly arranged at the bottom of the arched roof plate 302. The protruding section 302a located in the auxiliary chute 301c can be slid and adjusted more conveniently through the drag reduction sliding piece 301c-1, saving construction time and improving efficiency.
